To all whom it nmg concern:

Be it known that we, CHARLES GEORGE JoHANNEsMnYnR and ALFRED R.v MoOAnN,citizens of the United States, and residents,

5 respectively, of Glendale, in. the county of Hamilton and State ofOhio, and Hamilton,

in thecounty of Butler andtstate of Ohio, have invented certain new anduseful Improvements in Drip Pans, of whichthe following is aspecification. V

Our invention relates to novel drip pans which are more particularlyadaptedi'or use on metal planers' The objectsof our invention are. topro.

vide oil drip pans adapted to travel wit the planer table to the end oiits outward strokes and adapted to be returned part way therewith; toprovide means whereby the planer bed may be constructed considerablyshorter than the distance as measured from an outer end of the tablewhen extended in one direction beyond the end of planer bed to its outerend. when extended in the other direction beyond the end of the planerbed without the loss of oil in dripping from an extended end of theplaner table; to provide means whereby oil which drips from the planertable is returned to the main reservoir; to provide means wherebymovable drip pans are automatically extended by outward travel oftheplaner table and automatically returned to their normal positionswith the inward travel of the planer table; to reduce the expense inconstructing a metal planer and increase the available space for use forother purposes.

Our invention consists in adrip pan, preferably channeled, adapted toslidably re ceive an extendable drip pan having a perforatio-n in theend thereof adapted vto re ceive a hook or pin fixedto an end of theplaner table; further, in constructing said hook or pin in such a manneras to adapt it to returnsaid extendable drip pan to its normal position;further, in means fixed to the planer table and adapted to engage meansfixed to the planer bed whereby said pin or hook is induced to disengagesaid planer table; and further, in the construction, combination andarrangement of parts as herein set forth and claimed. I

and in addition showingthe planer table in engagement with the drippanFig. 7 is a transverse section taken on the line 77 of Fig. 4:;

. Fig. 8 is a perspective View showing our oil strainer in enlargedform; and y Fig. 9 is a side elevation showing our drip pan engaging pinor hook in enlarged form.

In the preferred construction of our invention 1 is a planer bed, 2 is aplaner table, 3 is a rack fixed to the planer table and actuated by theusualtrain of gears 4, 4t, 5 and 6 actuated by any suitable means.Planer table 2 has the usual longitudinal VS 7 adaptedto travel in theusual V track 8 in the planer bed, and the planer table is securedagainst upward movement by suitable mechanical means asat 9. The planerbed has reservoir 10 formed therein containing lubricating oil 11 inwhich the lower poi-- tion of gears 4, 4, 5 and 6 rotate. Reciprocatingmotion is imparted to planer table 2 by bull gear 4, meshing with. rack3 fixed to the lower portion of the planer table. Sufficient lubricationis provided for the rack and gear by teeth 12 of the bull-gearv carryingoil to teeth 13 of the rack from the oil reservoir. The portion of themechanism as described up to this point is of usual form by the bullgear to the rack and drips therefrom onto the planer bed, the topportion of which is slightly inclined toward the reservoir. The oil isinduced'to return from the top ofthe planer bed to the oil reservoir bygravitation." Considerable expense is thereby entailed in constructing aplaner bed having suflicientlengthto return the oil.

For the purpose of reducing the construction cost, the weight and spaceconsumedby a planer bed as Well as other objects herein specified, weprovide means whereby the oil l-roolc 22 fixed to the endlofth'e planertable is may be returned to reservoir as hereto-tore without thenecessity of constructing the planer bed of the usual length.

l/Ve preferably provide a drip pan 14 liked to each end 15 and 16ofplanerbed 1 and having channeled sides 17 adapted to slidably receivedrip pan 18 havingplate 19 fixed to its end 20. A hole 2-1 extendsthrough end 20land plate 19 for. receivii'i'g hook 22 fixed to the endof the planer, table 15 by any suitable means such as being threadedthereto. Wedge member 23 is fixed-t0 the lower end 20 of drip pan18-byscre'iv 24. At a predetermined point in the return movement of end25 of table 2 the angular surface 26 ot'the wedge member is adapted toengage angular surface 27 of wedge mam ber 28 fixed to the upper. end 25of bed 1 thereby elevating end 20 of the drip pan-for the purpose ofc'lis'engagin'gliook 22' 'fr'om hole 21 of the drip pan to permit thetable to continue its inward movement disengaged from drip pan 18. Pins29 fixed inbo'tto'm 30 of drip pan 1 1 are. adapte'd to stopinwa-rdmovement of drip pan 18 produced by momentum after hook 22iis'released from engagement withhole 21'of drip pan 18.

. O'il'strainer as shown in enlarged form in Fig 8 comprisesends 3,1 and31"and's1ides 32 and 32 secured together in any suitable manner and; hasa wire screen 83' or other Suitable material fixed to the bottom there'-of. Bolts 34 c'ombinedly received inholes in end 35 of drip pan 14'andholes 36' in cars 37 fixed to side 32 of the oil strainer secures theoil strainer in the position as shown in Fig. 1 to end 35 of drip pan14.- for the pur pose of separating toreigninatter from the oil thatdrips from rack 3 onto pans 141 and 18. v V

In operation the mechanism of our inven= tion is as follows: Rota-tablebull' gear 4:

meshing with rack 3 imparts reciprocating motion to planer table 2secured to the rack.

The end 25 of the planer table in its outward travelcaus'es'hook 22 toengage hole 21 in end 20 of drip pan 18 thereby sliding, drip pan 18outwardly to the extreme point of travel of the table whereupon bullgear 4t reverses its direction otrotation thereby cans: ing rack 3 toreverse the dire'ctionoftravel of the table. Hook 22 being in engagementI with end 20 ot drip pan 18 at hole 21 carries drip pan 18 inwardlyuntil angular surface 26 of wedge member 23fiXed to the lower end of thetable contacts angular surface 27 of wedge'member 28 fixed to the up perend of the bedthereby elei' ating end 20 of drip pan 18 and disengagingnookaanom the pan. The table continues 1 its inward movement -to apredetermined'point on the bed when the bull gear reverses its directionof rotation thereby causing the planer table to reverse its direction oftravel from in- Wa-rd motion to ou-twardmotion whereupon again projectedthrough hole 21" inzend 20 of drip pan 18 and the outer end of the tablecontacts the inner side of end 20 of drip pan 18 thereby pushing itoutwardly. This opera tion" is repeated with each reciprocating movementof the table thereby n'iaintaining drip pan 18 in position beneath rack3 for receiving oil which dripsfrom the rack. Drip pans 1 1'and--18areslfightl-y inclined-toward oi'lres'ervoir 10 and the oil iscaused by gravitation to flow inwardly toward'the resg ervoi-r throughoilstrainer' 30' free from inipnrity and foreign matter such as dirt,grit, etc. w

It is" noted that thereis a; fixed drip pan 14 on each end of bed l andalso a cooperating slidatieor telescoping drip pan 18 and of the beditcarries. with it in the direction it is moving the adjacent slid-abledrip. pan and'durin niatume the other s'lida'ble drip pan is standing inthe'pesition as shown at either endo'f Fig. 1. Thus the oil drippingfrom therack during the entire operations of the a table is eiiectivelycaught and returned to the oil reservoir;

While we have describcd'the details of the preferredembodiment; of ourinvention it is to be understoodthat it is capable of other adaptationsand modifications within the scepe of the claims.
